This patch fixes the below build error reported by Stephen,
Stephen reported:
After merging the drm-exynos tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/media/i2c/adv7604.o: In function `of_graph_get_endpoint_by_regs':
adv7604.c:(.text+0x586c): multiple definition of `of_graph_get_endpoint_by_regs'
drivers/media/i2c/adv7343.o:adv7343.c:(.text+0xa13): first defined here
drivers/media/platform/soc_camera/atmel-isi.o: In function `of_graph_get_endpoint_by_regs':
atmel-isi.c:(.text+0x1ec9): multiple definition of `of_graph_get_endpoint_by_regs'
drivers/media/platform/soc_camera/soc_camera.o:soc_camera.c:(.text+0x2ce3): first defined here
drivers/media/platform/soc_camera/rcar_vin.o: In function `of_graph_get_endpoint_by_regs':
rcar_vin.c:(.text+0x307c): multiple definition of `of_graph_get_endpoint_by_regs'
drivers/media/platform/soc_camera/soc_camera.o:soc_camera.c:(.text+0x2ce3): first defined here
Caused by commit:
a0f7001c18ca ("of: add helper for getting endpoint node of specific identifiers")
To fix the error, this patch declares of_graph_get_endpoint_by_regs function
with "static inline".
